In a bit of a rough shape, and no way to check the history or look for the certificate - everybody with that knowledge has passed

Says it's E56121.1, and I have no experience to tell if it's real or not. The battery is out, and while I'll do the AD service and get it working anyway, because of the personal connection to it, I'd like to know what I'm dealing with.
There are a few things that are different from the other Emergencies I've seen online:
* There are three extra buttons - one on the right, two on the left. Without the watch working, I can't tell what they'd be for - I'm guessing the one on the right by the antenna is probably the "test" button I've heard mentioned.
* The yellow logo on the left, where 9 goes. That's usually where the special edition images go, but I can't find this particular one documented anywhere.
Any thoughts? Fake, and if real, what's with the yellow jets on the left? (Photos are a bit fuzzy, hopefully doesn't make a difference.)
